Cladodionen, a Cytotoxic Hybrid Polyketide from the Marine-Derived Cladosporium sp. OUCMDZ-1635.

ABSTRACT: A new hybrid polyketide, cladodionen (1), together with a new abscisic acid analogue, cladosacid (2), were isolated from the marine-derived fungus, Cladosporium sp. OUCMDZ-1635. Their structures, including the absolute configurations, were fully elucidated on the basis of spectroscopic analysis, ECD spectra, quantum chemical calculations, and chemical methods. Cladodionen (1) showed cytotoxic activities against MCF-7, HeLa, HCT-116, and HL-60 human cancer cell lines with IC₅₀ values of 18.7, 19.1, 17.9, and 9.1 µM.
